 It's lovely this time of year. Shell Rotella's advanced synthetic technology also offers extended drain intervals, helping your rig go farther between oil changes. So you'll make less pit stops. Well, unless you need to restock on snacks, we really can't help you with that. But if you're looking to help your big rig engine live longer, look no further. Superior protection, less maintenance. That's what you can expect from the number one heavy-duty engine oil in North America. Shell Rotella for the long haul.
